- To find the area, you need to divide the shape into a rectangle and a triangle: The area of the rectangle is 5 × 4 = 20cm 2. The base of the triangle is calculated by subtracting the base of the rectangle (4cm) from the total length of the shape (10cm).

Area Different shapes have different ways to find the area. For example, in a rectangle we find the area by multiplying the length times the width. In the rectangle on the right, the area is 2×4 or 8. If you count the small squares you will find there are 8 of them. (See Area of a rectangle .).

Difference Between Parallelogram and Trapezoid Area of the parallelogram can be calculated by the product of the length of one side and the height to the opposite side. The area of the parallelogram is independent of the shape of individual parallelogram. It is dependent only on the length of base and the perpendicular height.

- To find the area of a parallelogram you have to find the height, which is not the slanted side, to find the height you have have to draw a line down from the highest point to … the base so it forms a perpendicular line on both the top and bottom sides. Then from here you just do base times height and that's your area.

- The volume of a right trapezoidal prism is equal to the height times the base area of the trapezoid. The area of trapezoid is $\frac{1}{2}$ h(a + b) and 'h' is the height of the trapezoid, not the height of the prism. If 'a' is the length of the top, 'b' is the length of the bottom. Then the formula for the volume of the trapezoidal prism is given below: Volume of a Trapezoidal Prism Formula The volume of a prism is given by the formula, V = Al Where A is the area of the base of the prism and 'l' is the length or height of the prism. => Area of trapezoidal prism = $\frac{1}{2}$ h(a + b) => Volume of the Trapezoidal Prism = $\frac{1}{2}$ h(a + b) x l = $\frac{1}{2}$ h(a + b)l Formula:

Calculating Area To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length 2 or length squared.he area of a triangle is (height × width) ÷ 2. In other words you can work out the area of a triangle in the same way as the area for a square or parallelogram just divide your answer by 2. The height of a triangle is measured as a right-angled line from the bottom line to the ‘apex’ (top point) of the triangle.

What is the midsegment of a trapezoid? The midsegment of a trapezoid is referred to as the median or the midline. The length of the midsegment is calculated by finding the average length of each of the parallel sides. The formula for this length is the sum of the length of side A plus the length of side B, divided by two. The midsegment is also used to calculate the area of a trapezoid. Learn more about Shapes.

What is the formula for the volume of a trapezoid? Volume of a Trapezoidal Prism. The volume of a right trapezoidal prism is equal to the height times the base area of the trapezoid. The area of trapezoid is 12h(a + b) and 'h' is the height of the trapezoid, not the height of the prism. If 'a' is the length of the top, 'b' is the length of the bottom.

Finding the Area of Trapezoids Remind students that the area of a rectangle is base × height; for the rectangle formed from the original trapezoid, the base is ½(b1 + b2) and the height is h, so the area of the rectangle (and, consequently, of the trapezoid) is A = ½h(b1 + b2). This is the traditional formula for finding the area of the trapezoid.
